Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] Such as Figure 1 to Figure 4 As shown, the engine oil pump structure of the present invention has an oil pump base body 1, an oil pump cover 2, an oil pump shaft 3, an oil pump driven gear 4, and a gear assembly mounted on the oil pump shaft 3 and located in the inner cavity of the oil pump base body 1 Or the rotor assembly, the oil pump base body 1 and the inner wall of the crankcase body 5 are integrally formed integral structure, and the oil pump driven gear 4 installed on the oil pump shaft 3 end meshes with the oil pump driving gear 7 on the crankshaft 6 . The oil pump seat 1 is formed by extending the boss from the inner wall of the crankcase body 1, and processing the oil pump cavity, oil inlet hole and oil outlet hole on the boss, and is processed and assembled separately with the traditional oil pump to form an assembly. Then, compared with ...

Abstract

The invention provides an engine oil pump construction which comprises an oil pump seat (1), an oil pump cover (2), an oil pump shaft (3), an oil pump driven gear (4) and a gear component or a rotor component. The gear component or the rotor component is mounted on the oil pump shaft (3) and arranged in an inner cavity of the oil pump seat (1); the oil pump seat (1) and the inner wall of a crank box body (5) are integrally formed; and the oil pump driven gear (4) mounted at one end of the oil pump shaft (3) is engaged with an oil pump driving gear (7) on a crank (6). The engine oil pump construction has compact structure of an engine, decreases the manufacture cost and obviously lowers the engagement noise between the oil pump driving gear and the oil pump driven gear.

Description

technical field [0001] The invention relates to equipment parts on engines, especially engine oil pumps. Background technique [0002] The oil pump is the core component of the engine lubrication system. It is used to pump a certain amount of lubricating oil from the oil pan and pressurize it, and then continuously send it to the surface of each part for lubrication, so as to maintain the circulation of lubricating oil in the lubrication system. Most of the oil pumps are installed in the crankcase and are driven by gears, driven by camshafts, crankshafts or timing gears. [0003] On the existing four-stroke engines, the rotor type oil pump is usually used which has the advantages of compact structure, large oil supply, uniform oil supply, low noise and high oil suction vacuum. The rotor, oil pump cover, oil pump shaft, oil pump driven gear, etc. are assembled into an assembly, and the assembly is installed on the engine when assembling the engine. In this way, the oil pump...
